# ACTION:

Final rule.

# SUMMARY:

The FAA is superseding Airworthiness Directive (AD) 2003-25-01 which applied to certain Eurocopter France (now Airbus Helicopters) Models AS332C, AS332C1, AS332L, AS332L1, AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, and AS355N helicopters. AD 2003-25-01 required modifying and re-identifying the hoist operator control unit and replacing certain fuses. This AD was prompted by the identification of multiple errors in the applicable service information for the AS350-series and AS355-series helicopters and of other needed changes. This AD retains certain requirements of AD 2003-25-01, revises the applicability, and requires using corrected service information. This AD also requires reporting certain information and prohibits the installation of an affected hoist until the required actions are accomplished. The FAA is issuing this AD to address the unsafe condition on these products.

# SUPPLEMENTARY INFORMATION:

## Background

                    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2003-25-01, Amendment 39-13384 (68 FR 69596, December 15, 2003) (AD 2003-25-01), for Eurocopter France (now Airbus Helicopters) Model AS332C, C1, L, and L1, AS350B, BA, B1, B2, B3, and D, and AS355E, F, F1, F2, and N helicopters with a Breeze 300 pound electric hoist (hoist) and hoist operator control unit 26M part number (P/N) 350A63-1136-00 or 350A63-1136-01, and hoist electric box 91M P/N 332A67-2875-00, installed. The NPRM published in the                     **Federal Register**                     on April 28, 2021 (86 FR 22363). In the NPRM, the FAA proposed to require modifying and re-identifying the hoist operator control unit, replacing the fuses, and performing a functional test of the hoist operation and the emergency jettison controls. The NPRM also proposed to require reporting certain information and prohibit the installation of an affected hoist until the required actions are accomplished.                

The NPRM was prompted by EASA AD 2019-0228, dated September 12, 2019 (EASA AD 2019-0228) to supersede DGAC AD 2002-585(A), dated November 27, 2002 (DGAC AD 2002-585(A)), issued by DGAC, which is the aviation authority for France. EASA, which is the Technical Agent for the Member States of the European Union, issued EASA AD 2019-0228 to correct an unsafe condition for Airbus Helicopters (AH), formerly Eurocopter, Eurocopter France, Aerospatiale Model AS 350 B, AS 350 BA, AS 350 BB, AS 350 B1, AS 350 B2, AS 350 B3, AS 350 D, AS 355 E, AS 355 F, AS 355 F1, AS 355 F2, and AS 355 N helicopters. EASA advises that Airbus Helicopters identified translation errors in the service information required for compliance by DGAC AD 2002-585(A). Airbus Helicopters was also informed that there could be helicopters modified by that service information with incorrect installations. Prompted by these findings, Airbus Helicopters revised the related service information. Therefore, EASA issued EASA AD 2019-0228 to require modifying and re-identifying the hoist operator control unit, replacing the fuses, and performing a functional test of the hoist operation and the emergency jettison controls as intended by DGAC AD 2002-585(A) with the revised service information. EASA AD 2019-0228 also requires reporting certain information to Airbus Helicopters and prohibits the installation of an affected part on any helicopter unless it has been modified.

The NPRM also retains the requirements from AD 2003-25-01 for Model AS332C, C1, L, and L1 helicopters with a certain hoist and hoist box installed, based on DGAC AD 2002-584(A), dated November 27, 2002.

                    Additionally, since the FAA issued AD 2003-25-01, the FAA discovered that the applicability needed to be revised. This AD revises the applicability by distinguishing the hoist box installations by P/N, clarifying that Airbus Helicopters service information refers to a hoist box as a hoist operator's control unit, adding TRW, Lucas, and Air Equipement hoists for affected Model AS350-series and AS355-series helicopters, and adding an exception for affected helicopters to exclude those with a certain modification (MOD) installed.                          ( print page 37232)    

Lastly, since the FAA issued AD 2003-25-01, Eurocopter France changed its name to Airbus Helicopters. This AD reflects that change and updates the contact information to obtain service documentation.

## Discussion of Final Airworthiness Directive

## Comments

The FAA received no comments on the NPRM or on the determination of the costs.

## Conclusion

These helicopters have been approved by both the authority of France and EASA and are approved for operation in the United States. Pursuant to the FAA's bilateral agreement with France and the European Union, DGAC and EASA have notified the FAA about the unsafe condition described in the ADs issued by each authority. The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these helicopters. With the exception of the minor editorial change of adding, “With a” in paragraph (c)(1)(ii) of this AD, this AD is adopted as proposed in the NPRM.

## Related Service Information Under 1 CFR Part 51

The FAA reviewed Airbus Helicopters Alert Service Bulletin (ASB) No. 25.00.71, Revision 2, dated May 14, 2019 (ASB 25.00.71 Rev 2), Airbus Helicopters ASB No. 25.00.79, Revision 3, dated September 24, 2019 (ASB 25.00.79 Rev 3), and Eurocopter ASB No. 25.01.18, dated November 12, 2002 (ASB 25.01.18). ASB 25.00.71 Rev 2 applies to Model AS355-series helicopters, ASB 25.00.79 Rev 3 applies to Model AS350-series helicopters, and ASB 25.01.18 applies to Model AS332-series helicopters. ASB 25.00.71 Rev 2 and ASB 25.00.79 Rev 3 specify procedures to install MOD 07 3190, which consists of eliminating resistor 27M in the hoist operator's control unit 26M and replacing the 2.5A quick-response fuses on the Honeywell unit at 30 alpha or 21 delta for Model AS350-series helicopters or on the distribution panel 10 alpha for Model 355-series helicopters. ASB 25.00.71 Rev 2 and ASB 25.00.79 Rev 3 also specify reporting certain information to Airbus Helicopters. ASB 25.01.18 specifies procedures to install MOD 332PCS 78 288, which consists of eliminating resistor 81M in hoist box 91M and re-identifying the hoist box as 332P67-2894-01, -02, -03, or -04, depending on which electrical wiring assembly is installed in the helicopter.

                    This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the                     **ADDRESSES**                     section.                

## Other Related Service Information

The FAA also reviewed Airbus Helicopters ASB No. 25.00.71, Revision 1, dated May 21, 2014 (ASB 25.00.71 Rev 1), and ASB No. 25.00.79, Revision 1, dated May 21, 2014 (ASB 25.00.79 Rev 1) and Revision 2 (ASB 25.00.79 Rev 2), dated May 14, 2019.

ASB 25.00.71 Rev 1 specifies the same actions as ASB 25.00.71 Rev 2, except ASB 25.00.71 Rev 2 provides a reminder that MOD 07 3190 is mandatory and adds a reporting response form. ASB 25.00.79 Rev 1 and ASB 25.00.79 Rev 2 specify the same actions as ASB 25.00.79 Rev 3, except ASB 25.00.79 Rev 2 provides a reminder that MOD 07 3190 is mandatory and adds a reporting response form and ASB 25.00.79 Rev 3 adds Model AS350L1 to the effectivity.

## Differences Between This AD and the EASA AD

EASA AD 2019-0228 applies to Model AS350BB helicopters, whereas this AD does not because that model is not FAA type-certificated. EASA AD 2019-0228 requires modifying affected parts within 100 flight hours or 2 months, whichever occurs first, whereas this AD requires these actions before next flight involving a hoist operation for Model AS350-series and AS355-series helicopters instead.

## Costs of Compliance

The FAA estimates that this AD affects up to 977 helicopters of U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates that operators may incur the following costs in order to comply with this AD.

Modifying and re-identifying the hoist operator control unit, replacing the fuses, and functionally testing the hoist operation and the emergency jettison controls takes about 4 work hours and parts cost about $20 for an estimated cost of $360 per helicopter and up to $351,720 for the U.S. fleet.

For Model AS350-series and AS355-series helicopters, reporting information takes about 1 work-hour for an estimated cost of $85 per helicopter and up to $82,195 for the U.S. fleet.

## Paperwork Reduction Act

A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a currently valid OMB Control Number. The OMB Control Number for this information collection is 2120-0056. Public reporting for this collection of information is estimated to take approximately 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. All responses to this collection of information are mandatory. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden to: Information Collection Clearance Officer, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-1524.

## Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority.

The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: General requirements. Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.

## Regulatory Findings

This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify that this AD:

(1) Is not a “significant regulatory action” under Executive Order 12866,

                    (2) Will not affect intrastate aviation in Alaska, and                          ( print page 37233)    

(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
